What is LANDU's main product?
LANDU specializes in cellulose ethers (HPMC, HEMC, HEC) and VAE redispersible polymer powders (RDP) for construction, food, and pharmaceutical applications.
What is cellulose ether used for in dry-mix mortar?
Cellulose ether improves water retention, workability, and open time in tile adhesives, wall putty, gypsum plaster, and self-leveling compounds.
What viscosity of HPMC is best for tile adhesive?
For standard tile adhesive, 40,000–70,000 mPa·s HPMC is recommended. Higher viscosity provides better sag resistance and longer open time.
What does RDP powder do in construction materials?
RDP forms a flexible polymer film that enhances adhesion, flexibility, crack resistance, and water resistance in mortars, plasters, and tile grouts.
Where is LANDU's production base located?
LANDU operates three manufacturing sites in China with 75,000-ton annual capacity, serving customers across 60+ countries worldwide.
Does LANDU offer free samples for testing?
Yes, free samples are available for lab evaluation. Contact our team with your application requirements and target viscosity grade.
What is the difference between HPMC and HEC?
HPMC offers thermal gelation and better sag resistance, while HEC has stronger salt tolerance and hydrophilic properties—making each suited for different formulations.
How should cellulose ether be stored properly?
Store in sealed containers below 25°C with humidity under 60%. Avoid direct sunlight to prevent moisture absorption and clumping.
Is LANDU REACH certified for the European market?
Yes, LANDU products comply with ISO 9001 and EU REACH standards, with dedicated production capacity for the European market.
Can LANDU customize cellulose ether for specific formulations?
Yes, LANDU offers tailored solutions through our R&D center, including modified viscosity grades and hydrophobically treated variants for unique application needs.
